systemd

systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, supports snapshotting and restoring of the system state, maintains mount and automount points and implements an elaborate transactional dependency-based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit.

The Biggest Myths of systemd

Since we first proposed systemd for inclusion in the distributions it has been frequently discussed in many forums, mailing lists and conferences. In these discussions one can often hear certain myths about systemd, that are repeated over and over again, but certainly don’t gain any truth by constant repetition. Let’s take the time to debunk a few of them.

Revisiting How We Put Together Linux Systems

In a previous blog story I discussed
Factory Reset, Stateless Systems, Reproducible Systems & Verifiable Systems,
I now want to take the opportunity to explain a bit where we want to
take this with
systemd in the
longer run, and what we want to build out of it. This is going to be a
longer story, so better grab a cold bottle of
Club Mate before you start
reading.

Traditional Linux distributions are built around packaging systems
like RPM or dpkg, and an organization model where upstream developers
and downstream packagers are relatively clearly separated: an upstream
developer writes code, and puts it somewhere online, in a tarball. A
packager than grabs it and turns it into RPMs/DEBs. The user then
grabs these RPMs/DEBs and installs them locally on the system. For a
variety of uses this is a fantastic scheme: users have a large
selection of readily packaged software available, in mostly uniform
packaging, from a single source they can trust. In this scheme the
distribution vets all software it packages, and as long as the user
trusts the distribution all should be good. The distribution takes the
responsibility of ensuring the software is not malicious, of timely
fixing security problems and helping the user if something is wrong.

Linux kernel D-Bus implementation

V2 Of KDBUS Published For Linux Kernel Review

The second revision to the Linux kernel based D-Bus implementation is now available for review.

Greg Kroah-Hartman on Thursday night posted the “v2” revision of the KDBUS implementation for providing the kernel with a new IPC implementation that resembles the existing user-space D-Bus daemon while adding extra features.

systemd 217 Updated In Debian & Soon Making Its Way To Ubuntu 15.04

systemd 217 brings many features and is currently the latest systemd stable release. Systemd 217 brought its experimental user console daemon, support for job timeouts, logind enhancements, udev updates, KDBUS handling improvements, and a plethora of other work.

CoreOS is building a container runtime, Rocket

We thought Docker would become a simple unit that we can all agree on.

Unfortunately, a simple re-usable component is not how things are playing out. Docker now is building tools for launching cloud servers, systems for clustering, and a wide range of functions: building images, running images, uploading, downloading, and eventually even overlay networking, all compiled into one monolithic binary running primarily as root on your server. The standard container manifesto was removed. We should stop talking about Docker containers, and start talking about the Docker Platform. It is not becoming the simple composable building block we had envisioned.

Fedora 21 Is Coming In Just Two Days With Big Improvements

Fedora 21 is the first release of the Fedora.Next initiative that separates Fedora out into three products: Fedora Cloud, Fedora Server, and Fedora Workstation. These new Fedora “products” are fairly self explanatory and it’s the Fedora 21 Workstation that most users will be after who want Fedora as a desktop operating system.

Fedora 21’s Performance Is Close To Ubuntu 14.10

Fedora 21 is due out in a few days and as such I’ve been busy extensively testing and benchmarking this first Fedora Linux update in a year. To not much surprise given the close package versions to Ubuntu 14.10, Fedora 21 isn’t performing very differently from the Ubuntu Utopic Unicorn.

Mike and Chris battle wits to expose the ridiculous nature of arguing about technology on the Internet, and this discuss why developers and enthusiasts get caught up in this mess.

Plus our take on working on open source in your spare time, an update on teaching students to code & a software pick that will make you hungry!

Dev Hoopla:

The Story of the PING Program

Yes, it’s true! I’m the author of
ping for UNIX.
Ping is a little thousand-line hack that I wrote in an evening which
practically everyone seems to know about.

I named it after the sound that a
sonar makes, inspired by the whole principle of echo-location.
In college I’d done a lot of modeling of sonar and radar systems,
so the “Cyberspace” analogy seemed very apt.
It’s exactly the same paradigm applied to a new problem domain:
ping uses timed IP/ICMP ECHO_REQUEST and ECHO_REPLY packets
to probe the “distance” to the target machine.

Pick of the week:

A command line application that will automatically order you a sandwich from Jimmy John’s.

makemeasandwich.js

This is a Node.js application that is capable of ordering a Jimmy John’s sandwich via command line, bringing to life this legendary XKCD comic.

It does this through the combination of Node.js + PhantomJS along with some other command line prompt tools that makes ordering a sandwich even more freaky fast.

Debian’s Choice

What is systemd? To quote the homepage: \”systemd is a system and session manager for Linux, compatible with SysV and LSB init scripts. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux cgroups, supports snapshotting and restoring of the system state, maintains mount and automount points and implements an elaborate transactional dependency-based service control logic. It can work as a drop-in replacement for sysvinit.\”

— Debian: to systemd or upstart? —

Whether Debian chooses systemd or Upstart has major implications on the future too, so you shouldn\’t only look at what is now, but also keep in mind what will come next. And there are at least two areas where opting for Upstart will mean you shut out Debian of major changes.

— systemd criticism —

Systemd is a one program \’garbage dump\’ of a lot functionality which used to be provided with shell scripts and special tools (aka badly designed, insofar UNIX(*) design rules go) and it consumes more memory doing nothing than sysvinit.

The systemd journal is in a binary format .

I fucking hate this new system. Its a mess of scripts that call on more scripts. Its such a pain in the ass now if you want to have a program run when the system starts. Gone are the days of just adding a line to /etc/rc.local

If you need access to the raw journal data in serialized stream form without C API our recommendation is to make use of the Journal Export Format, which you can get via \”journalctl -o export\” or via systemd-journal-gatewayd. The export format is much simpler to parse, but complete and accurate. Due to its stream-based nature it is not indexed.

— systemd home turf advantage —

No CLA
Used as an API by more and more projects (logind, timedated, localed, hostnamed, udev, more..)
cgroups (aka control groups) is a Linux kernel feature to limit, police and account the resource usage of certain processes (actually process groups). Compared to other approaches like the \’nice\’ command or /etc/security/limits.conf, cgroups are more flexible. Cgroups can be handled natively by systemd
Some Debian designs pushed into systemd as defaults, like setting the hostname and others that the devs felt Debian did better than other distros.
